Costco and other firms that filed early lawsuits may have an edge when it comes to collecting any refunds.

The decision is a stinging defeat for Trump — and three conservative justices voted against him.

Trump, as recently as Thursday, has talked up the consequences of the Supreme Court striking down his tariffs prior to the seismic ruling.

Supreme Court Justice Brett Kavanaugh, in his dissent, warned that "the refund process" for tariffs "is likely to be a 'mess,' " citing oral arguments

The Supreme Court ruling that President Trump's tariffs are illegal will lead companies to seek billions in refunds, but the decision was silent on the issue.

The ruling opens the door to potentially hundreds of billions of dollars in tariff refunds.

The US Supreme Court ruled that 'reciprocal' tariffs imposed by the American president were illegal.

Matt Totsch, the CFO of manufacturer Trim-Tex, said businesses like his have been dealing with crippling uncertainty caused by Trump’s chaotic tariff policies.

Sen. Elizabeth Warren (D-Mass.) said consumers, not big corporations, should get refunds.

Costco and other firms that filed early lawsuits may have an edge when it comes to collecting any refunds.

At least 1,000 companies have already sued the administration of United States President Donald Trump.

The Supreme Court's decision has led questions over whether people can get a refund over the unlawful tariffs.

The court did not say how the government should refund the illegal tariffs, worth an estimated $175 billion.

Efforts to claw back the estimated $133 billion to $175 billion of previously collected tariffs now deemed illegal are bound to be complicated.

Refunds were not addressed by supreme court ruling, and they’ll likely play out in lower courts over extended period

Treasury Secretary Scott Bessent expressed doubt that households would receive any money raised by tariffs: “I got a feeling the American people won’t see it.”
